In this utility model, firstly, a classification and cleaning mechanism is arranged inside. This structure can realize the classification and cleaning of different clothes at one time, which is convenient for the daily operation of the user and reduces the consumption of water resources, thereby improving the energy saving of the washing machine. Secondly, the drum adopts a detachable structure, which is convenient for the installation and disassembly of the drum, which is convenient for the maintenance of the washing machine and the daily disassembly and cleaning of the drum. In the process of realizing this utility model, the inventor found that the prior art has the following problems:

[0004] In the existing drum washing machine, when the drum is rotating at high speed, the centrifugal force affects the clothes in the drum, causing shaking and consuming rotational kinetic energy. When the clothes are unevenly distributed in the drum, the centrifugal force on one side will be greater than that on the other side, causing the drum to vibrate and shake, and at the same time generate noise. The force generated by the eccentric rotation requires the motor to consume additional energy to overcome, thereby increasing the rotational driving force and increasing energy consumption.

[0005] Therefore, in order to solve the above problems, a vibration-reducing, low-noise, high-torque, energy-saving direct-drive drum washing machine is proposed. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] As shown in the attached Figures 1 to 4 A shock-absorbing, low-noise, high-torque and energy-saving direct-drive separate-barrel washing machine shown, including a laundry body 1, a laundry drum 4, a dehydration drum 5 and a shock-absorbing and noise-reducing component 6. A laundry chamber 2 is opened at the upper end of the inner cavity of the laundry body 1, and a dehydration chamber 3 is opened at the lower end of the inner cavity of the laundry body 1. The laundry drum 4 is arranged in the inner cavity of the laundry chamber 2, the dehydration drum 5 is arranged in the inner cavity of the dehydration chamber 3, the shock-absorbing and noise-reducing component 6 is respectively arranged on the outer surfaces of the laundry drum 4 and the dehydration drum 5, and sealing doors 13 are arranged on the left sides of the laundry chamber 2 and the dehydration chamber 3;

[0025] The shock-absorbing and noise-reducing component 6 includes an installation ring 601. The installation ring 601 is arranged on the outer surface of the laundry drum 4. There are three groups of installation rings 601. The inner surface of the installation ring 601 is provided with pulleys 602. There are four groups of pulleys 602. The inner surface of the laundry chamber 2 is provided with slide rail grooves 603. There are three groups of slide rail grooves 603. The outer surface of the dehydration drum 5 is equidistantly and spacedly provided with another three groups of installation rings 601. The inner surfaces of the other three groups of installation rings 601 are all installed with another four groups of pulleys 602. The inner surface of the dehydration chamber 3 is provided with another three groups of slide rail grooves 603.

[0026] Wherein: when the laundry drum 4 and the dehydration drum 5 rotate in the laundry chamber 2 and the dehydration chamber 3 respectively, the sealing door 13 is closed. Through the three groups of installation rings 601 arranged on the outer surfaces of both the laundry drum 4 and the dehydration drum 5, pulleys 602 are installed. Each group of installation rings 601 is installed with four groups of pulleys 602. Thus, when the laundry drum 4 and the dehydration drum 5 rotate at high speed, the pulleys 602 abut against the slide rail grooves 603. The pulleys 602 will rotate together with both the laundry drum 4 and the dehydration drum 5, and thus rotate along the tracks of the three groups of slide rail grooves 603, so that the laundry drum 4 and the dehydration drum 5 maintain balance during rotation, avoiding the shaking phenomenon caused by uneven load and the change of the center during rotation.

[0027] Embodiment 2

[0028] On the basis of Embodiment 1, the solution in Embodiment 1 will be further elaborated in combination with the following specific working modes, as Figures 1 to 4 shown, and the details are described below:

[0029] As a preferred implementation manner, an electromechanical compartment 7 is opened on the right side of the washing machine body 1. The inner cavity of the electromechanical compartment 7 is provided with two direct current brushless motors 8; further, due to its structural characteristics, the direct current brushless motor 8 can provide high-efficiency torque output. Through the direct drive design, a greater torque transmission can be achieved, and the washing and dehydration processes can be driven more effectively.

[0030] As a preferred implementation manner, drive shafts 9 are connected to the centers on the right sides of both the laundry drum 4 and the dehydration drum 5. One ends of the two drive shafts 9 are respectively connected to the output ends of the two direct current brushless motors 8 through penetrating the electromechanical compartment 7; further, the output ends of the direct current brushless motors 8 are connected to the drive shafts 9, thereby driving the drive shafts 9 to rotate. When the drive shafts 9 rotate, they will drive the laundry drum 4 and the dehydration drum 5 to rotate, thus achieving the direct drive effect.

[0031] As a preferred embodiment, a water inlet pipe 10 is provided at the upper end on the right side of the laundry chamber 2, and a first drain pipe 11 is provided at the lower end on the right side of the laundry chamber 2. An electric valve 111 is provided at the center of the first drain pipe 11, and a second drain pipe 12 is provided at the lower end on the right side of the dehydration chamber 3. Further, an external water source is connected through the water inlet pipe 10 to guide water flow into the laundry chamber 2. When drainage is required, the electric valve 111 is controlled to open through the control system, so as to discharge the sewage, and the second drain pipe 12 discharges the water in the dehydration chamber 3.

[0032] As a preferred embodiment, the outer surface of the pulley 602 abuts against the inner surface of the slide rail groove 603, and the pulley 602 is movably connected to the mounting ring 601 through a rotating shaft. Further, the pulley 602 abuts against the slide rail groove 603 to be closely attached thereto. The pulley 602 is connected to the mounting ring 601 through a rotating shaft, so that the pulley 602 can rotate by itself. When the drum rotates, it will drive the pulley 602 to rotate and rotate along the slide rail groove 603.

[0033] The working process of the present utility model is as follows: First, when starting the washing machine body 1, the sealing door 13 is closed by rotating the hinge. Subsequently, an external water source is connected through the water inlet pipe 10 to guide water flow into the laundry chamber 2. The output end of the DC brushless motor 8 in the electromechanical compartment 7 drives the transmission shaft 9 to rotate through the connecting transmission shaft 9. When the transmission shaft 9 rotates, it will drive the washing drum 4 and the dehydration drum 5 to rotate, so as to achieve a direct drive effect. When the washing drum 4 and the dehydration drum 5 rotate in the laundry chamber 2 and the dehydration chamber 3 respectively, three groups of mounting rings 601 are arranged on the outer surfaces of both the washing drum 4 and the dehydration drum 5 to install the pulleys 602. Each group of mounting rings 601 is provided with four groups of pulleys 602. Thus, when the washing drum 4 and the dehydration drum 5 rotate at high speed, the pulley 602 is connected to the mounting ring 601 through a rotating shaft, so that the pulley 602 can rotate by itself. When the drum rotates, it will drive the pulley 602 to rotate and rotate along the slide rail groove 603, so that the washing drum 4 and the dehydration drum 5 are supported and rotated around by the shock absorption and noise reduction assembly 6 during the rotation process and keep balanced, thereby avoiding the shaking phenomenon caused by uneven load and the change of the center during rotation. When drainage is required, the electric valve 111 is controlled to open through the control system, and the sewage is discharged from the first drain pipe 11. Since the dehydration chamber 3 is used for dehydration, the second drain pipe 12 is always in an open state to discharge the water in the dehydration chamber 3 at any time. The above is the working principle of the shock-absorbing and low-noise large-torque energy-saving direct-drive separate-barrel washing machine.

[0034] Finally: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
